Repro-1 (out now)

[Urs]

I'd laugh my ass off if Urs released this on April 1st and all five models were the same filter.

Nah, I would *never* do that

Interesting, so even with all the mixer levels turned to 0 there's still some amount of signal passing through the filter. I guess that does make sense for a good analogue emulation.

That's the filter CV bleeding through into the audio signal. I couldn't resist modeling this as it is rather pronounced in CEM3320 configurations and certainly part of its distinct "fizzy" sound.

I think you've given away a bit too much info now though.

It's present in all filter methods, but we had to cap filter frequency at 25kHz. The final version - if we take the accurate model - will go to 50kHz such that the filter can fully open within the audible range. I would not take the pseudo-aliasing bit as any indicator for anything. I'm just saying, this filter is extreme and much of what sounds like aliasing may not be that

(I also think it'll be necessary to make a video with some live tweaking of a Pro-One to demonstrate some of its sonic crazies)

Ah, good to know. A video would be great! I've never had any hands on time with an actual Pro-1, so I really have no idea what it's supposed to sound like.

FILTER 1 is close but to noisy,
FILTER 4 is the PRO-ONE!

Number 4 is Noisy but not to much ,
remember the Vince Clarks percussions

Too bad he is using reverb (or slight delay) on there.

Woah... this one sounds completely different from ours!

[Mono-Amine]

Filter one comes closest to the pro-one i borrowed and was a guest in my studio for a couple of months

I like sound of filter 4 aswell

Thank you urs for destroying the myth of "objective listening" with that cool plugin really enjoying this thread

Liking filter 4 the best at the moment.

It's a cool sounding synth. You should hunt those guys down!

It lacks bottom end authority of an analog, otherwise filters 2-5 all sounds really very nice and even 1 would be just fine. Volume differences between the filter models makes comparisons a bit iffy, and on most actually used settings differences between 2-5 are way too small to make any difference whatsover. At more extreme settings the differences become more obvious, but as the character of the filter is the same, I'd be tempted to say that the additional detail probably isn't worth the CPU hit. In the end the they all sounds like algos anyway, #5 was my favourite.

I agree to 100%

So far my experience has been that I can like just about any of these depending on the setting except 3, which sounds too much like 2 and 4 without the character 4. Filter 5 sounds the cleanest, but it's also dull sounding (i.e. boring) IMO. Number 1 has really started to grow on me, even though it can be a bit too wild at times. 4 is a nice balance between nasty and controlled. Still couldn't pick a favorite (maybe 1 then 4, sometimes it's 2), but my initial impressions went from thinking 1 is terrible to really starting to like it. Maybe it's just the volume differences at lower resonances, but it's really growing on me.

Urs, I'd definitely like to hear what your Pro-One sounds like at some more extreme settings/resonances to get a feel for what's intended.

Filters and sound aside, the brown background color of the preset browser seems to be too much for my Macbook - at least for the display. It's kind of swirling/flickering all the time (don't know how to describe this properly...). Reminds me somewhat of those old CRT displays. Anyone else noticed something similar? Or is this part of the analog emulation as well? (Just kidding... ).

That sounds like a flaw typical of many TN Panels. TN panels are only 6 bit, IE red, green, and blue only have 64 values.

They employ tricks to look like 8 bit (256 values of RGB), which is what a typical desktop (mac or PC) uses. The tricks can be seen as patterns or flickering at certain colour values depending on the TN panel and methods of trickery they implement.

Certain shades can also reveal problems with power regulation to the panel at certain settings, and this applies even to non-TN panels (though mostly TN - did I mention they're evil? ) In those cases just changing the brightness may "fix" it..

Many thanks for your answer, this could perhaps be the point since my Macbook isn't the newest one. Unfortunately, changing the brightness didn't solve the issue, whether brighter or darker. Guess I'll use the preset system of my DAW for now, at least for the Alpha

1 Aliases a lot with high res + freq, so that is out, to my mind - irrespective of whether people like the sound of that (and it has it's place tbf) you wouldn't get that one a Pro1, so, bye.

The tuning variance of the rest (particularly 4) makes things a lot less clearer cut. I think 3 uses a cheaper AA method as the uppers seem quite tamed out (maybe, anyway, for whatever reason, it all seems to vanish a bit in the very high end). I'm leaning towards 2 or 5, maybe. Probably 2. But 4 is definitely throwing a spanner in the works.

I'll vote when I'm ready and thought it through a bit more.

Hehehe, that isn't aliasing, that is the resonance still being there and locking in with the harmonics of the oscillators. People in the office also came over and said "Uh, it aliases like hell". Then I pressed a key on the Pro-One with same settings and "uh, ok".

OK so I've been wrong
